I just subscribed to the Guitar Noise Podcast. In the first episode, managing editor David Hodge goes through some of the basics of strumming. If you’re just learning the guitar, as I am—my parents gave me a guitar over the holidays, then I recommend you check it out.
I hope that, as they get a little more familiar with the technology, they will take advantage of dividing their podcasts into chapters and then show relevant “artwork” such as a JPG of the strumming pattern or chords that they want you to hit. But as it stands now, it’s still a great example of using podcasts for teaching.
(Yes, I realize in order to use chapters the podcast needs to be in AAC format instead of mp3, but as an iTunes user, it’s a trade-off that works for me. Perhaps they could have two streams, a normal podcast and an enhanced m4a version.)
